Question

A line passes through the points (-2, 2) and (3, -3). What is the equation of this line in slope-intercept form?

A. y = 3
B. y = x – 2
C. y = x + 2
D. y = –x

Answer 1

D. y=-x

Explanation:

y=mx+b

m=slope = (-3-2)/(3+2)=-1

The line passes through (-2,2)

2=-2(-1)+b

b=0

Answer 2

D. y = –x

Explanation:

2 = - (-2)

- 3 = - (3)
